Abstract
(EN)
Disclosed is a fused ring compound having the structure as represented by formula (I) or formula (II). In the fused compound, by controlling an effective conjugate of an aromatic ring and a heterocycle, while increasing the hole performance of the compound, balanced electron transport performance is favored. The compound is provided with a high triplet state and glass state transformation temperature, the material molecules of the compound are not prone to crystallization, and the compound serving as the main material of a light-emitting layer ensures highly efficient transfer of energy to an object material. An adjustment of a substituent group of the fused ring compound further increases electron and hole transport performances, reduces the difference between a singlet state and a triplet state, expands a compositing area for a carrier, and prevents triplet exciton annihilation. Also disclosed is an organic electroluminescent component having at least one function layer containing the fused ring compound. The fused ring compound serves as the main material of the light-emitting layer, matches with an adjacent carrier transport layer in terms of energy level, and, while increasing the luminous efficiency of the component, reduces a driving voltage for the component.

L'invention concerne un composé cyclique fusionné ayant une structure telle que représentée par la formule (I) ou la formule (II). La présente invention permet de contrôler de manière efficace la conjugaison d'un cycle aromatique et d'un hétérocycle du composé fusionné, ce qui permet d'améliorer la performance des trous de celui-ci et d'équilibrer la performance du transport d'électrons. Le composé présente un état triplet élevé et une haute température de transition vitreuse, les molécules du matériau du composé ne sont pas sujettes à la cristallisation, et le composé peut être utilisé comme matériau principal d'une couche électroluminescente, ce qui permet d'assurer un transfert hautement efficace de l'énergie vers un matériau cible. L'invention permet d'adapter des groupes substituants du composé cyclique fusionné, ce qui permet d'améliorer encore les performances de transport d'électrons et des trous, de réduire la différence entre l'état singulet et l'état triplet, d'élargir la région de composition des porteurs, et d'éviter l'extinction des excitons à l'état triplet. L'invention concerne en outre un composant électroluminescent organique comprenant au moins une couche fonctionnelle contenant le composé cyclique fusionné Le composé cyclique fusionné fourni par la présente invention peut servir de matériau principal pour une couche électroluminescente, correspondant à une couche de transport de porteurs adjacente en terme de niveau d'énergie, permettant ainsi d'améliorer l'efficacité d'émission de lumière du composant et de réduire la tension de commande de celui-ci.
